I need a little help understanding something. I was wondering if it is possible to understand the physics behind sled pulling? From what I can tell is there are two major factors in pulling 1) being the coefficient of friction needed to move the sled (14,000lbs of weight over 2, 5'x1' pieces of rubber,) 2) the wheelspeed of the tractor needed to maintain that coefficient of friction (the greater the wheelspeed the more the tire melts and grip is lost.) Is something like this possible to figure out? Has it been looked at before? What other information do I need to gather or supply to determine the solution?
